Tumbleweed Whenever you think of the Wild West of America, you think of cowboy movies and tumbleweed, perpetually tumbling around a desolate landscape.
Salt lowers the freezing/melting point of water, so in both cases the idea is to take advantage of the lower melting point. Ice forms when theÂ­ temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 F (-6 C), and a 20-percent solution freezes at 2 F (-16 C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it. The salt dissolves into the liquid water in the ice and lowers its freezing point.
Salt will melt (become liquid) at 801 degrees Celsius, 1074 degrees Kelvin, 1474 degrees Fahrenheit. It will vaporize at 1465 degrees Celsius, 1738 degrees Kelvin, 2669 degrees Fahrenheit. 801 degree Celsius or 1074 Kelvin It will melt when heated above this temp. It will freeze when cooled below this temp.
